<h2>Right answer: Sea breeze </h2>
The sea breeze is formed because during the day the surface of the land on the coast tends to warm up before and more than the surface of the sea. This difference in temperature between these two air masses means that on a sunny day the land warms up much more than the ocean causing a small area of low pressure.
Then, the air rises as the land warms it and the colder air located on the surface of the sea forms a high pressure zone that makes this air mass tend to occupy the space left by the warmer air that has ascended on the coast. Therefore, the mass of air of a high pressure on the ocean always tends to move towards the zone of low pressure located on the coast.
It is important to note that the <u>sea breeze blows perpendicularly to the coast</u> and that the best breezes are formed in the spring and summer seasons because during the spring the water temperature is still cold and during the summer the sun produces high temperatures over the land in the coast.
<h2>So, <u>
the greater the temperature contrast </u>
between the land and the sea, <u>
the greater the force of the wind generated</u>
.</h2>
Heat required to raise the temperature of water is given as
here we have
m = 100 g = 0.100 kg
s = 4183 J/kg C
now we can use the above equation
so here it requires 20920 J heat to raise the temperature of 100 g water by 50 degree C

This question is a big fat non sequitur !
The wavelength of radio waves traveling through vacuum only depends on the frequency that the radio station is licensed to broadcast on, (which had better be the frequency of the transmitter that they buy and use, or they're in big trouble).
The wavelength does NOT depend on the type of modulation that's used to put information onto the signal.
An amateur radio (ham) operator may very well start out using FM to talk over his radio to somebody else, and then for some reason they may decide to switch to AM. They can do that without ANY change in the wavelength of their transmissions.
Now, in the USA and many other countries, it so happens that all AM stations are licensed by their governments to transmit their programs on a channel somewhere between 500 KHz and 1.6 MHz, and all FM stations are licensed by their governments to transmit their programs on a channel somewhere between 88 MHz and 108 MHz. (And THAT's what the radio receivers in these countries are built to receive.)
Then we might say that all of the AM stations are grouped around 1 MHz, and all of the FM stations are grouped around 100 MHz. The FM frequencies are very roughly 100 times the AM frequencies, so the AM wavelengths are very roughly 100 times the FM wavelengths. That's <em>choice (3)</em> .
But please don't get the idea that it has anything to do with using AM or FM technology. It's just a matter of where in the spectrum the government decided to put the AM stations and where they put the FM stations.
For that matter . . . An analog TV station uses an AM signal for the picture and an FM signal for the sound, and it all goes in the same channel, with just about the same wavelengths !
Violet light is at the end of the visible light section of the electromagnetic spectrum. Ultraviolet rays are directly next to violet rays on the EM Spectrum.
